ASLEEP Mattress Only Double with Summer/Winter Covers

We are offering a high-quality mattress from ASLEEP, a brand by Aisin (Toyota Group).

It features Aisin's unique and innovative Fine Revo material, which offers gel-like softness and flexibly conforms to your body's movements, supporting an ideal sleeping posture. It provides an exceptionally comfortable sleep, as if you're floating on water.

Although the brand's business has ended, its high quality continues to make it a sought-after item.
Due to shipping constraints, this listing is for the mattress only. However, the bed frame is available on a separate page, so please consider purchasing both.
The winter cover for this mattress has some pilling on the surface (see 5th photo).
This is why we have priced it lower.
The summer cover is new.
